They’re the triangular facets in the corners.

Just adding to the @GridMonster….Windmills are an older cutting style. Top has windmills due to that cut-corner. The wider the cut, the bigger the windmills.

No windmills. The facets meet at a 45 degree junction. This is technically a “rectangular step cut” example.

Ascher’s are a derivation of a Emerald cut with really wide windmills, square and they are technically an octogon.
